EDGE-FOLDING IVZACHINE POCKET-BOOK BODIES.

Application filed October 16, 1916.

To alt HVILONL it wmg/ concern:

Be it known that I, WALTER C. EIorIEL- Bnnann, a citizen of the UnitedStates, and resident of lVestBend, in the county of iVashington andState of Wisconsin, have invented certain new and useful Improvements inEdge-Folding Machines for Pocket-Book Bodies; and I do hereby declarethat the following is a full, clear, and exact description thereof.

My present invention relates to new and useful improvements in machinesfor folding the edges of the bodies of pocket books, particularly thatclass which have hinged metal jaw pieces secured to the edges of the boddie of the principal objects of the inven tion is to provide a verysimply constructed machine whose operation will be very efficient andspeedy.

An additional object is to provide a machine, the parts of which are soarranged that the edges of the piece of work naterial being operatedupon will be simultaneously forced inwardly into the proper position andpressed between a heating member and a movable body member normallysupporting the material.

A still further object is to provide a novel arrangement of bendingplates and means for quickly actuating the same.

With these and many other objects in view, the invention resides in thenovel features of construction, combination and arrangement of partswhich will be hereinafter more particularly described and claimed.

In the drawings:

on the line '5-5 of Fig. 1 through the pressing and heating member ofthe machine.

Figs. 6 and 7 and 8 are partly diagrammatic views showing successivesteps in the folding and pressing operation of the machine, theoperation being carried out with out the use of the die blocks 9 inorder to simplify the illustration.

Fig. 9 is a transverse sectional view through the pocket book body asfolded by the machine.

Fig. 10 is a plan view of the body as folded.

Referring now more particularly to the accompanying drawings, theembodiment of my machine therein shown includes a bed plate 5 which isheld in spaced relation above a table support 6 by depending edge wallportions 7 which serve to house a portion of the folding mechanism. Theintermediate portion of the bed plate is downwardly offset to provide arecess 8 for receiving the pocket book bodies to be folded. To adapt therecess for operative reception of various sizes of pocket books, saidrecess has detachably seated therein the die block 9 the top face ofwhich is flush with the top face of the bed block, this block beingprovided with a recess 10 the area of which corresponds to the area ofthe desired size of pocket book bodies when folded.

The edge bending means comprises a pair of flat side bending plates 11slidable on the bed plate 5 and disposed forwardly and rearwardly of thedie block recess 10 and adapted for movement longitudinally of the axisof the machine, these plates being adapted to bend the side edgeportions of the pocket book body and being held for proper slidingmovement by upstanding guide flanges 12 at the side edges of the bodyplate 5 and slidably disposed over the end portions of the side bendingplates 11 are end bending plates 13 adapted for movement inwardly of theend portions of the recess to bend the ends of the pocket book body, theplates 11 being provided between the plates 13 at their inner portionswith upstanding en- I 13 whereby simultaneous inward movement of all theplates is permitted.

tions of the plates 11 and 13 are provided with slots 17 and 16respectively, extending at angles to the slots 15 and ,intersectlng saidslots. Through the intersection of each set of slots 15, 16, and 17 ispassed a bolt 18 projecting below the top wall 5 and hav ng mounted onits lower end a link 19 having its inner end pivoted to and extendingtangentially from the peripheral portion of a plate 20 which'isjournaled on a bearing sleeve 21 carried centrally by the off setportion of the bed plate 5. Thus upon rotation of the plate 20 the bolts18 will be simultaneously drawn inwardly and will exert a cam action onthe edges of the slots 16 and 17 of the bending plates to simultaneouslymove said plates inwardly.

To effect rotative movement of the plate 20, an arm 22 projects radiallytherefrom and outwardly of the bed plate wall througha slot therein.Secured to the link and to a pin 24 on the casing is a retractile spring25 which normally urges the rotative ac- 1 tuating plate 20 to aposition wherein the folding plates are in. retracted or initialposition. The plate 20 is rotated tomove the bending plates to operativeposition by a cable 26 secured to the arm 22 and extending forwardly ofthe machine and about a pulley 27 at its forward end and thencedownwardly for attachment to a pivoted treadle 28.

To raise the pocket book body coincident with actuation of the bendingplates 11 and 13 whereby the edge portions of the body are properly fedfor bending operation a false bottom 2.) is slidably fitted in therecess 10 of the die plate 9 and a shaft 30 projects outwardly therefromthrough the bearing sleeve 21 and is ap'ertured at its lower end for theloose reception of one end of an intermediately pivoted lever 31 whichhas its other end apertured to loosely receive a rod 32 extendingdownwardly through a slot '33 in the table 6 for pivotal engagement withthe treadle 28. A head 34 is formed at the upper end of this rod andadapted to abut the lever to swing it and thus raise the false bottom 29in the recess subsequent to the initial portion of opera tive movementof the bending plate. The

movement of this false bottom 29 also serves conducting material andprovided with a cured by links 42 pivoted thereto and to crank arms 43on a shaft 44 journaled'horizentally in the bed casing. This shaft beingactuated by a handle arm 45 projected therefrom.

pressing and heating action at the edge portions of the folded pocketbook bodies the intermediate bottom portion of the block 35 is cut awayand fitted in this cutaway 7 portion is a preferably wooden block 46 tothe bottom face of which is secured a thin metallic plate 47, the edgeportions of which project under the edge portion of the block 35. Toadapt the heating and pressing member also as a guide means for theedges of the work material during the bending operation thereof, inwhich instance itis not desired to exert a heating operation the block46 is slidably mounted in the cut away portion of the block 35, beingheld therein and resiliently urged to retracted position by a leafspring 48 secured to its inner'face and having its ends engaged inpassages 49 formed in the block. Pivoted to an up standing ear 50 at therear end of the casing is a bar 51 which extends through and isvertically slidable in a transverse passage 52 formed in the block 35inwardly of the a block 46 and this bar extends forwardly of thepressing and heating member and is notched at its forward end forengagement with a hook member 53 which is manipulated by means of itspivotal connection with a plate 54 vertically slidable in a guidechannel 55 on the front bed plate wall, and this plate is connected withthe treadle 56 below the table by a link 57. V V l Taking up now theoperation of the entire machine a flat pocket book body is first laidover the recess 10 of the die block 9. A flat holding plate 58 is placedon the body member and pressed to force the body mem bar into therecess10, this plate being of but slightly less area than the area of therecess whereby the pocket book body and plate are frictionally held bytheir disposition in the recess this phase of the operation beingindicated in Fig. 6. The handle 45 controlling the pressing and'heatingblock 35 is then swung forwardly to depress said block, and the treadle56 is depressed to swing the hook 53 into interlocking engagement withthe bar 51. The handle 45 is then partially lifted to raise the block 35from the bed 8O Inasmuch as it is only desired to exert a V 7 i isprocured.-

plate and work material, the block 4L6 and guide plate a7 being retainedin lower position by reason of the hook 53. The operator then depressesthe treadle 28 to operate the Y, bending plates 11 and 13 and to raisethe false bottom 29 of the recess as heretofore described, it beingnoted that the plates 11 and inc inwardly between the bed plate and theplate 457 wl ereby exact folding lV th the bending treadle stilldepressed, the operator then pulls downward with considerable s ig'thupon the handle 45 thus pressing the rolded pocket book body between theraised false bottom 29 and the heating and pressing block 35, thisposition being retained for a suiiicient length of time to heat andsufliciently press the pocket book body to permanently retain the foldstherein. During these pressing operations the treadle 56 controlling thehook 53 is released and upon the pressing operation being completed thehandle 45 is swung backwardly lifting the heating and pressing block 35and the folded pocket book body is removed, the plate 58 beingsubsequently detached therefrom.

In removing the die block 9 for replacement of another die block havinga different shaped recess 10 to accommodate pocket book bodies ofdifierent shape it is obvious that it is necessary also to providesubstitute sets of plates 11 and 13 and substitute false bottoms 29.
